Sinchana 

The pretty bestie, immaculate sense of fashion, great taste in music, cat mom, chill and go with the flow type of person. Although she's an introvert, she would never turn down an opportunity to party with her friends. She most likely has a tiny appetite but the way to her heart is through food. But then again, she'll only accept the food if it's from her fictional crush.

Wow, she looks like an ethereal goddess. she's must be a Sinchana.

Sinclaire 

The funniest girl you will ever meet. Very athletic but can be chill and lazy too. Fun to hang around ! Finding a Sinclaire is 0.5 in 2 million!! Never take her for granted she can make your life a living hell if you do.

I saw Sinclaire over the weekend I had the best time ever! You should have been there.
